I am curious as to the components of FDRs that allow them to sustain such g-forces and immense heat. Surely it's not just a steel box filled with paraffin wax. What alloys are used? what shapes are used in internal construction to prevent crushing/penetration? What do they insulate with and how is it layered? How is the SSD secured in the chassis? Is the chassis pieced together or cut from a single piece of metal? I apologize for so many questions in one post, but I am genuinely curious about how these and similar pieces of technology work. I am ultimately seeking an example of the materials used and they way they are combined. Thank you for all of your help.
